'This invention relates to utility devices or appliancesv and more particularly to electrically driven'power appliances for use aboutA the home.

There'are numerous instancesin which a powered hand tool is useful' in performing household tasks, in hobby crafts, and in making minor repairs and alterations about the home. It is impractical to have a large or bulky device, and the expenseand inconvenience of storing and caring for a number of such tools is not attractive to the average family.

It, is therefore, one`of the principal objects of the present invention to provide a new and improved economical household utility appliance which is capable of beingV used in the performance of numerous tasks and yetoccupies a minimum of space vand can be readily moved about.

A more specific object is to provide an economical electric utility device which is 'portable and incorporates va flexible sheathed drive'cable, normally retracted', and which vcan'be extended for use as desired.

` Another robject is toy provide in a household utility, 'the combination of av rotatable drive arbor or shaft for fixed position devices suchv as buffers, grindstones, and the'like, and a iiexible sheathed drive'cable which can be used alternatively to 'drive buffers, grinders, drills scouring brushes, and the like.

Al further object is to provide in an electrically powered flexible shaft' devicehaving a reel for carrying the exible shaft in retracted position and from which the flexible shaft can be extended for use, a control responsive to the position of the cable or the reel for governing the electric drive motor to prevent driving of the cable when the latter is retracted.

A further object is to provide in a combination device having an arbor and a flexible drive shaft powered by a common motor, means for automatically disconnecting the flexiblev drive shaft from the motor when the arbor is used.

A still further object is to provide a poweredV utility appliance which is relatively simple; in design Aand construction and inexpensive to manufacture., The invention will be found to embody numerous features which reside in novel combinations and arrangements of parts. Additionalobjects and advantages will become apparent as the description' proceeds. In the drawings:

Fig. 'l is a fragmentary sectional detail taken substantially on the line'` 1-1 of Fig. 6; and

Fig. 8 is a fragmentary vertical sectional detail showing the control mechanism and switch.

Referring to -the drawings by numerals of reference which indicate like parts throughout the several views, the'deviceV comprises an elongated enclosing casing or housing having an arched top or cover portion I and a lower upright skirt portion 2 continuous with the arched top. The particular shape of the casing is not critical but is preferably formed with smooth contours, so that it canbe readily kept clean and will not have sharp corners to catch or snag the clothing of the person using the device. A handle 3 secured to the casing top I provides for carrying the device from placeto place. v

Within the casing, which also serves as part of the supporting frame structure for the device,

is a supplementalV crossA frame 4 secured by screws 5 to the under side of inwardly extending brackets B formed on opposite sides of the interior of the casing.v Rubber cushions orrings are interposed between the screws and the brackets. The supplemental frame includes a transverse upstanding portion 1 havingformed thereon a journal boss 8 which generally parallels the cross frame 4 and is bushedY to rotatably receive one end of shaft 9 of an electrical drive motor. The supplemental frame 4' also carries an electric drive -motor 23 lfor the appliance. This motor'may be of commercial make, but is preferably constructed as an integral part of the appliance. A combined motor casing and yoke I0, integral with the supplemental frame 4 and continuous with the upstandingvjournal support 'I receives motor field windings II and armature windings I2, the latter being secured on the motor vshaft 9 in accordance with conventional armature construction. The end of the motor yoke I0, opposite the journal 8, is formed with a circular opening having an annular shoulder I4. A combination member including a tubular journal portion I5 and a motor end bell portion I6 is disposed in axial alignmentY about the motor shaft. The large diameter end of the bell por- The outer-end ofthetubular portion I5 .of

The tubular portion I5 ofthe motor end membermaybe formed with an external lateral bossY 4I recessedto receive the inner endof the shaft 33 4(Fig. 3).

The adjustable pin 29 is directed-downwardly toward the motor shaft 9 through an opening V35 in the upper part of the tubular vportion vI5 of themotor'end member, On the lowerend of the pin 29 is formed a coned detent portion 3l which rides in a circumferential channel-or groove y33 (Fig. 5)- formed about `the toolsupporting arbor I9. ThisV interlockingconnection 'between the detent pin 29 and the tool arborretains the latter inwdriving relation to the motoreshaft 9 to be actuated thereby.- The pin 29 can ,be raisedto clear the channel A38 for axial removal of the-'toolV supporting sleeve arbor outof its socketby-moving a lever 39-mounted on the shaft 33/externally of the casing. The lever A39,'seeured on theshaft33 as by pin 40 is actuable-to rotate the shaft and the lever 3|, thus raising the arm- 30 -and vwithdrawing the detent pin 29vthrough the opening 35 4 30 and the detent screw 29 moved to the position shown in Fig. 8.

A number of the tool supporting arbors or sleeves I9 may be provided, mounting different types of tools such as buffers, polishers, brushes andftheglike.v Thus the-variousrimplements or toolscan beireadily interchangediwithione another in the driving socket of the device for use asvdesired.

A Beneath the supplemental frame 4 in that portion of-the internal chamber of the device which issurrounded-by the/.skirt 2 of the casing is disposed a reeljf42'j-mounted for rotation about a normallygupright'axis which is at a 90 degree .angle to the motor shaft 9. Y A central sleeve portion*43of"thereel is fitted with anti-friction bushings #44 and 45 which rotatably receive a supporting and cable driving shaft 45.

A gear l5 in the chamber 'I3 is secured on the cable 65 to drive the latter. The teeth of the gear l5 mesh with a worm 16 formed on the reel drive shaft 46. Rotation of the drive shaft 46 through the gears 52 and 55 upon energization of the electric motor is imparted to the flexible cable v|55 through the worm 16 and gear 15. y

The outerend of the flexible cable-sheath combination is carried throu'ghva anged' sleevev 18 secured in an apertured boss formed'in the skirt 2 of the casing. yThe sheath lis slid'able through the-sleevev 18 in extending the cable'for use and in retracting the cable and sheath onto'the reel. Externally of the casing the sheath Yis attached to a handle Bwhich journalsa shaft-8| secured to the end of the ilexible cable 65. The shaft 8| is threaded to receive a nut82-which retains a grinder 83V or similartool mounted thereon against the shoulder of an integral flange 84 formed on the shaft 8|, thereby locking the tool in place to rotate with the shaft.y

Disposed about the journal boss 5l and located between the cross frame 4 and the upper side of the reel 42 is a helical coil flat leaf .spring 85, inner end 89 of which is received. inazradialslot formed in the boss 5|. 'The outer end ofthe spring is formed into a loop 81 received on a pin 8S secured in the upper side of the reel 42. vRo tation of the reel in extending the sheathed vc able twists the spring 85 storing energy therein which operates to reversely rotate the reel forretraction of the cable.

A helical channel or groove 99 is formed in the upper side of peripheral ilange 62 of the reel and guidingly receives the lower. end ofv va pin .9| carried in a slide 92 positioned; and supported between guides 93 formed on the underside of the cross frame 4. The slide 92 is thus supported for straight line reciprocating movement radially with respect to the reel axis and during the rotation of reel 42 in extending and retracting the sheathed cable.

Rotation of the reel in extending the cable occurs in a counterclockwise direction viewed from above in Fig..6, and the pin 9| guided in the helical channel 99 moves-from left to right (Fig. 5) shifting the slide 92 in the; same direction. A cap 94 telescopically. mounted on a finger 95 carried by the slide Yis thus brought to bear against actuating button 96 of an electrical control switch 97 carried by bracket IUI secured to the motor end member. 94, under the influence of a helical coil compression spring 99 contained therein, acting against the switch button 96 actuates the-switch, which is of conventional construction, toclose the electrical circuit which energizes the drive motor of the device as will later appear. Extension of the sheathed cable kthus may be made to operate automatically to eiectenergization of thev electrical drive motor. The switchv control slide 92 prevents driving of the'cable except when the cable is extended for use. This feature prevents excessive loads beingv imposed on the electric motor by inadvertence. The internal friction in the sheath and cable combination is considerable when they are in the form of a coil. Itis uneconomical and impractical to provide an electric motor of suicient power to drive the coiled cable and the smaller electric motor providedfor normal. use would likely-be damaged if `energized with the cable in retracted position. By the?,v

The pressureof the cap present arrangementdamage to the motor is avoided.

To vretain `the reel 42 in cable extended position, the outer end of the helical channel 99 is.

formed witha radial offset-.providing a shoulder 98`which, when the cable is fully extended, is enhead end' ofthe cap and the end of the finger 95 reacts against the button of the electric switch 91 to shift the slide 92 in a reverse direction and to move the pin 9| into the radial offset portion of the channel 99. .Across pin |00 secured in the finger on the slide 92 and extending into elongated Vslots in the tubular cap 94 retains the cap on the ringer.

To release the latch or detent pin 9| from the shoulder 9B to permit retraction of the sheathed cable by the energy stored in the spring 85, a lever |92 is actuated. This lever is secured on a pivot pin |93 retained for'horizontal swinging movement of the lever in a boss .|94 formedin the supplemental cross frame 4 and suspended by a washer |95 and pin |06. The lever extends laterally through a slot opening |93 inthe skirt 2 of the casing and its inner end is formed with an open endedslot .|01 which receives or embraces the rdetent pinn9l. During movement of the pin from theinner end of the helical channel Seto the shoulder 98 at. the outer end of the channel and as the sheathed cable is extended, the lever |92 swings in a counterclockwise direction from approximately. the full line position to the broken line position indicated in Fig. 6.

The pin 9| is released from :the shoulder 98 by actuating theleverp|92 tomoveit in a counterclockwise., direction, asv viewedA from r`alcove,

sufficiently to .withdraw theljpin 9| from the shoulder 98. `The reel 42l is then yfreewtoyberotated clockwise by the spring r85. Y Provisionpis. made for optional actuationo either .the sheathed cable or the 'tool mounting sleeve arbor I9 bythe electricalAmotor.. When the sleeve-.arbor is,-to be used, the driving connection between `the motor and the sheathed cable is interruptedv by moving the bevel gear 56 axially alongthe motor shaft 9Y to the left `as viewed in Fig. 5 to the positionthere shown. Such movement is'eifected by a yoke |99 which is received in a circumferential groove orl channel i9 formed in the hub of the gear 56. The yoke is secured on a rod lll slidable in a sleeve l|2 formed on the upper end of a pedestal |4carried by the cross frame 4. The rod which is thus movable along an axis-paralleling the rotational axis of the motor shaft'9v is formed with pivot endl 5 to which is pivotally connected one end of a link |56. ally carried by apinrlllisecured inthe lever .Si which carries the supporting armi'30 previously mentioned in connection with: thei ,adjustable detent screw 29. yWhentthe gears" 52and 59 are engaged for actuation of theflexible drive cable by the motor, `the lever 3| :anddetentzpin 29 are positioned as shownzin Eig. 8;

Movement of the lever r3| in a` counterclcckwise direction as from .the position of FigfS to the position of Fig. `5 thus cperates'to shift the slide rod and thek bevel gear 56 to the left, disengaging such gear from. the reel drive gear 52. This disengaging of the gears 'may Ybe effected either' byfactuati'n of the lever 39 externally oftheA casing. or byinsertion' of the ltool VThe other end ofthe link is pivot- Y of the manualV lever39. `only prevents driving of theflexible cable 65y in I ofthe motor; .Inthewlattencase theV coned end 20 of the tubular sleeve I9 moves into-tubular portion .l I5 of l' the, motor end member :and engagesthe 'conedlend131 lon" the adjustable retainingscrev/FZS. fIThe angularity of the cones and .the :offset .positionY ofi the pivot 'axis .of the shaft-33 causes :the screwr29 to ride` up and along theconical end of the sleeve,'causingrotation of the :lever 13| Iand' effectingv gear. vdisengaging moveinenteofpthe linkage. andthe -slide WhenLthe'tool supporting s1eeve'or'arbor-|9 has beenfthus moved' into' the tubular' portion I5 of the motor end .member to operative position, the detent sc1'ew129 drops into the annular groove 38 to vretainthe `arbor in .the socket. A'tension spring ||3 is connected betweenthe-slide and the boss 4| on the motor endsmember to yieldingly hold the bevel gears 52 .andV 55 in driving engagement.

A downwardly.' extending .-curved. arm ||8' is pivotallycarried by theiA lever shaft-33 and is positionedibetween the vhubof the'lever 3| and `the journal boss 4|.

The rheostat-switch device isactuated by a shaft which extends through an opening in the casing and carries a hand wheel |29 formanipulation externally of the'. casing.

- Fig. 4 shows a suitable wiring diagram for the device, electrical current Abeing furnished through a two wire cable containing conductors LI and L2. The conductor-LI is connected'by a wire or conductor |2| toyone terminal Vof `the motor'28.
